IEC 62560 Clause 15 Circuit Of Figure 8 For Non-Dimmable Lamps For Testing self-ballasted Lamp

Product information:

The test circuit for testing a non-dimmable lamp is manufactured according to IEC62560 clause 15 figure 8.

Standard description:

15.Abnormal operation

Self-ballasted lamps shall not create hazard under abnormal operating conditions.

Self-ballasted lamps shall be constructed so that as a result of abnormal or careless operation, the risk of fire and mechanical damage impairing safety of protection against electric shock is obviated.

Appling non-dimmable self-ballasted lamps on a diameter or an electronic switch is to be tested as a possible case of abnormal operation.

Test procedure:

Test non-dimmable lamp in test circuit shown in figure 8.

Determine R1 and S1 setting at which the maximum I r.m.s occurs.

Test at this situation, and if the lamp passively fails within 60 min, repeat the test at 10% lower I r.m.s. The lower I r.m.s shall be set in the decreasing potentiometer resistance direction.

Repeat these procedures until stable operation is achieved for minimum 60 min.
